What this trial studies

This interventional trial compares three treatment approaches for adults with androgenetic alopecia: thulium laser alone, thulium laser with a topical growth-factor serum, and thulium laser with growth-factor serum combined with LED phototherapy. Participants are adults aged 18 and over without scarring alopecia or major contraindications and will receive treatments and scheduled follow-up visits at a single center. Outcomes include objective hair measurements and patient-reported hair and scalp satisfaction to capture both clinical and patient-side effects. The protocol excludes pregnant or breastfeeding women, recent resurfacing procedures, metallic head implants, significant scalp wounds, and other specified contraindications.

Who should consider this trial

Good fit: Adults aged 18 and older with non-scarring androgenetic alopecia who are in good general health and able to attend clinic visits are ideal candidates.

Not a fit: People with scarring or non-androgenetic hair loss, recent scalp resurfacing, significant open scalp wounds, metallic cranial implants, or who are pregnant or breastfeeding are unlikely to benefit from this intervention.

Why it matters

Potential benefit: If successful, this approach could provide a minimally invasive option to increase hair density and improve patient satisfaction for people with pattern hair loss.

How similar studies have performed: Some small studies and clinical experience suggest laser and growth-factor combinations may help hair regrowth, but robust, controlled evidence is currently limited.
